An Effect of Wind Veer on Wind Turbine Performance
International Journal of Renewable Energy Development, 2023 An investigation was performed to identify the wind veer impact on wind turbine power performance at a wind farm located on Jeju Island, South Korea. A 2 MW wind turbine was used as a test turbine.

Delay-Optimal Buffer-Aware Probabilistic Scheduling with Adaptive Transmission
, 2015 Cross-layer scheduling is a promising way to improve Quality of Service (QoS) given a power constraint. In this paper, we investigate the system with random data arrival and adaptive transmission.

Powerful Power Curves: A production-proven, open-source schema for wind turbine power curves
, 2023 Digitalisation and seamless data exchange are vital for reducing time-to-market for new wind turbines, time-to-development of new wind farms, and workflow friction in collaboration between internal and external teams. However, power curve documents contain highly sensitive data - access to which should be carefully managed for good commercial and ...

The modification of wind turbine performance by statistically distinct atmospheric regimes
Environmental Research Letters, 2012 Power production from wind turbines can deviate from the manufacturer’s specifications due to variability in atmospheric inflow characteristics, including stability, wind shear and turbulence.

Accurate Short-Term Power Forecasting of Wind Turbines: The Case of Jeju Island’s Wind Farm
Energies, 2017 Short-term wind power forecasting is a technique which tells system operators how much wind power can be expected at a specific time. Due to the increasing penetration of wind generating resources into the power grids, short-term wind power forecasting ...

Maximal curves from subcovers of the GK-curve
, 2015 For every $q=n^3$ with $n$ a prime power greater than $2$, the GK-curve is an $\mathbb F_{q^2}$-maximal curve that is not $\mathbb F_{q^2}$-covered by the Hermitian curve. In this paper some Galois subcovers of the GK curve are investigated.

A new family of maximal curves [PDF]
, 2018 In this article we construct for any prime power $q$ and odd $n \ge 5$, a new $\mathbb{F}_{q^{2n}}$-maximal curve $\mathcal X_n$. Like the Garcia--G\" uneri--Stichtenoth maximal curves, our curves generalize the Giulietti--Korchm\'aros maximal curve ...

Power Curve Modeling of Wind Turbines through Clustering-Based Outlier Elimination
Applied System Innovation, 2023 The estimation of power curve is the central task for efficient operation and prediction of wind power generation. It is often the case, however, that the actual data exhibit a great deal of variations in power output with respect to wind speed, and thus

Multivariate Wind Turbine Power Curve Model Based on Data Clustering and Polynomial LASSO Regression
Applied Sciences, 2021 Wind turbine performance monitoring is a complex task because of the non-stationary operation conditions and because the power has a multivariate dependence on the ambient conditions and working parameters.

Does immigration affect the Phillips curve? Some evidence for Spain [PDF]
, 2007 The Phillips curve has flattened in Spain over 1995?2006: Unemployment has fallen by 15 percentage points, with roughly constant inflation. This change has been much more pronounced than elsewhere.
